New product introduction | Delta- LTL-3000

Since its establishment more than a few decades, Denmark DELTA has been committed to the development of new technologies of products in road traffic safety testing equipment with its strong technical force in the fields of acoustics and optics. In the product line it produces, each product is constantly striving for excellence, and it has been repeatedly praised and recognized in every user experience and market test.

In order to further adapt to the convenience and efficiency of modern equipment testing; further improve the efficiency of the testing industry; further optimize the user's operating experience of using the equipment.

DELTA once again achieved a major breakthrough in 2020. Base on the original technical performance, the actual volume of the equipment was greatly reduced, the original weight of the equipment was greatly reduced, and achieved true lightness and efficiency detection.

Product features

LTL3000 is part of a new generation of DELTA retroreflectometer instruments for measuring retroreflection of road markings. The instrument is based on the latest technological developments and with modern design and materials. LTL3000 is, like all other DELTA instruments, very easy to calibrate and operate, we like to say “very user-friendly”. And the instrument is of course robust and long lasting – like our earlier generations of road marking retroreflectometers – and on top of this small in size (420 x 300 x 150 mm / 16.5 x 11.8 x 5.9 inch) and light in weight (4.7 kg / 10.4 lbs.).
LTL3000 is primarily intended for users who need an instrument for less demanding measurement programs, who want an instrument which is easy to transport and who do not need many features to support the measurements.

The instrument complies with international standards:
China standards: GB/T 16311-2009
International standards: EN1436, ASTM E1710, ASTM E2177, ASTM E2302, ASTM E2367

Features:

-Simultaneous measurement of night visibility RL and day visibility Q d under dry and wet conditions
- Measures RL on profiled markings up to 15 mm / 0.6 inch
-Memory capacity up to 8 GB
- Multiple language
- Easy-readable color touch LED display with 3 buttons
-USB memory stick interface
- Power supply, standard Bosch professional battery, convenience to change on site

The LTL-3000 has the same automatic stray light compensation function as other DELTA reticle retroreflectometers. Sunlight and other external light sources will not affect its measurement accuracy . LTL3000 measure all types of road markings at a simulated distance of 30 m with a high accuracy. The instrument operates with a reproducibility of +/- 5 % and a repeatability of +/- 2 %.

New functions

Measuring chromaticity coordinates (x, y)

LTL-3000 can measure nighttime chromaticity coordinates (x,y) according to ASTM E2367 and CIE 1931. LTL-3000 measures the color of night reflected light-CIE chromaticity, which can measure the chromaticity performance of white and yellow marking lines. The color coordinate is one of the important contents of chromatics. The measurement of the color coordinate of the light source is one of the important methods to study the characteristics of the light source. In studying the chromaticity performance of the marking, it also plays an important role in guiding the marking to drive safely.

The LTL-3000 optical receiver is composed of three detectors that match the three-color sensitivity functions X, Y and Z of the human eye. The light reflected from the road markings is received and analyzed from the three receivers, including the 3 signals X , Y and Z to calculate the chromaticity coordinates:

Calibration method in accordance with international standards
The LTL-3000 instrument is RL calibrated by DELTA in the Danak laboratory of Denmark according to ISO17025 and ensures traceability to PTB (Physikalisch-Technische Bundesanstalt) and NIST (American National Institute of Standards and Technology).

Smaller and lighter transport case
Based on the smaller product size of LTL-3000, the size and weight of its transport box are also greatly reduced on the original basis, which is more convenient for on-site transportation and use, greatly increased the convenience of actual operation.
